If you’re looking to upgrade your engine’s PCV system, the APR PCV Top Plate is definitely worth your attention. This isn’t just any replacement part; it’s inspired by factory racecar tech and designed with a multi-step approach to tackle some of the common issues that can really hold back performance and compromise engine safety. Trust me, if you’ve experienced the headaches of oil vapors messing with your octane levels, you’ll appreciate what this piece brings to the table.

The heart of this upgrade is the new billet top plate that replaces the factory PCV. It’s built to address those pesky failure points that can lead to bigger problems down the line. One standout feature is the internally baffled chamber that effectively separates oil, which is crucial for keeping your engine running smoothly. Plus, the stainless steel oil drain back port is a nice touch, ensuring you’re not left with unwanted oil buildup.

Now, if you’ve ever tried to fit larger hoses in a tight engine bay, you know how frustrating it can be. That’s why APR includes new mounting pegs to lift the full-length engine covers out of the way, making installation a breeze. And let’s not forget the one-way check valve that prevents pressure from messing with the N80 valve—this little addition can save you from some serious boost leaks.

When it comes to the specs, all the fittings are -10 AN, which is a solid choice for performance applications. The complete billet aluminum top plate, combined with T304 stainless steel for oil separation and drain back, really shows that this part is built to last. The precision-fit bracketry ensures everything lines up perfectly, giving your engine bay a clean and professional look.

As for fitment, this plate is compatible with a range of Audi and Volkswagen models, including the Audi A3, S3, Q3, and TT, as well as various Volkswagen models like the Golf GTI and Jetta. Just keep in mind that this isn’t a full system; it’s meant as a replacement part for the MS100199 Full Catch Can System. And a quick heads-up: it won’t work with PCV systems that have the integrated blow-by sensor found in certain engines.

In short, if you’re serious about performance and want to prevent oil starvation or engine failure—especially in high-G situations—this APR PCV Top Plate is a solid investment. It not only enhances performance by reducing those octane-lowering oil vapors but also adds a touch of style to your engine bay. It’s a smart upgrade for anyone who knows the value of a well-functioning engine.
